Odaily Report: Monad co-founder Keone Hon posted on X stating that 0x published an interesting yet critical article this morning exploring an emerging phenomenon that first appeared in PropAMM (proprietary AMM) and has now spread to Uniswap v4 Hooks.In short, malicious market makers switch back and forth between "extremely narrow quotes" and "extremely wide quotes." They use extremely narrow quotes to attract aggregators into selecting that trading venue; however, once a user's trade is actually routed there, the quote immediately switches to an extremely wide spread. Slippage settings (i.e., limit protection) can protect some users—causing the trade to simply fail—but many users set slippage tolerance too high, and those users suffer extremely brutal "exploitation"—the article points out that certain Hooks maliciously switch back and forth between 0% and 18% fees.A few months ago, Solana also published a very insightful article analyzing a similar phenomenon occurring on Solana aggregators, though the fee cap was around 1% rather than 18%. A few days later, they quietly took the article down.The vision of an open system is to eliminate intermediaries and hidden fees. "Aggregator Spoofing" constitutes a massive hidden tax burden, and this problem can only be truly solved through fully-on-chain order routing. In turn, on-chain routing requires abundant computational power and flexible account access mechanisms—requiring both an extremely high-performance and efficient EVM and a well-designed on-chain routing protocol.Earlier this morning, 0x posted stating that the number of malicious Uniswap v4 Hooks has increased significantly recently. Some Hooks offer attractive prices during the inquiry phase but change the execution price at actual settlement, thereby stealing funds from users through aggregators, wallets, and trading applications.

Odaily News: DEX aggregator 0x has stated that the number of malicious Uniswap v4 Hooks has increased significantly recently. Some Hooks offer attractive prices during the quote phase but alter the execution price at settlement, thereby stealing funds from users through aggregators, wallets, and trading applications.0x stated that after analyzing 84,163 Hooks across 6 chains, it found that as of September 11, only 19.4% were deemed safe, 54.2% were deemed malicious, and another 26.4% were likely malicious. For some trades routed through malicious v4 Hooks, users received up to 50% less in assets than the quoted amount at actual execution.0x stated that since the beginning of this year, it has routed 81.92 million transactions with a trading volume of $42.67 billion, approximately 70% of which involved Uniswap liquidity. Currently, 0x has implemented measures such as detection and liquidity pool screening to prevent related malicious liquidity pools from entering trade routing.

Concurrently, Bitget Wallet has integrated 0x Protocol's Swap API into its own Swap API to further expand liquidity sources, providing users with better quotes and more stable execution quality. The initial integration will support multiple mainstream EVM networks including Ethereum, BNB Chain, Base, Arbitrum, and Polygon.To date, Bitget Wallet Swap has served over 5 million users with a total trading volume exceeding $30 billion. 0x Protocol has facilitated over 210 million transactions with a total volume surpassing $180 billion, serving more than 14 million unique wallets.

Odaily News Matcha Meta posted on X platform stating that it has noticed a security incident related to SwapNet. Some users who disabled "One-Time Approval" on Matcha Meta may have been affected. They have currently contacted the SwapNet team, which has temporarily disabled its contracts. After review with the 0x protocol team, it was confirmed that this incident does not involve 0x's AllowanceHolder or Settler core contracts. Users interacting with Matcha Meta via the one-time approval method can continue to use it safely. To prevent similar situations from recurring, the feature allowing users to directly set limits for the aggregator has been removed.Previous news reported that SwapNet experienced a security vulnerability, resulting in the theft of approximately $16.8 million worth of cryptocurrency.

According to Odaily Planet Daily, Venn Network security researcher deeberiroz revealed that Coinbase had a misconfiguration in its swapper contract with the decentralized exchange protocol 0x, resulting in a MEV bot stealing approximately $300,000 in token fees. The contract, originally designed for executing transactions, was not designed to receive token authorizations. After Coinbase mistakenly authorized it, the bot called the contract and transferred tokens from the Coinbase fee account. Coinbase Chief Security Officer Philip Martin confirmed the incident, stating that the issue stemmed from adjustments to the company's DEX wallet and did not affect customer funds. The team has revoked the authorization and transferred the funds to a new company wallet. (The Block)
